So which type of burner is better? The 20x Yamaha which uses P-CAV has been reviewed, how does the quality of the burn compare to a Zone-CLV burner? I mean the clearly visible Zones on the burned CD makes me wonder why they're visible in the 1st place. John, plz help

The cirles are visible so only some media...With other are not visible. No manufacturer till how has given an explanation but it must be something with the angle which the laser burns the disc. I think it changes slight the angle when shifting speeds.

As for your question, which is better than other... Soon we will have the answer
